Question

The centripetal force required for the revolution of a planet around the sun is provided by the gravitational force acting on the planet due to the sun.

• A. True
• B. False

Answer 1

The correct option is A True

1. According to the universal law of gravitation, the sun attracts the planets around it with its gravitational force.
2. The planets revolve around the sun in circular orbits.
3. A body that is moving in a circular path must constantly change its velocity and direction.
4. According to Issac Newton, the force that maintains an object to travel in a circular path is Centripetal force.
5. So, there must be a centripetal force acting on the planets to make them travel along the circular orbits.
6. This centripetal force is provided by the gravitational force of the sun on the planets.

Hence, the given statement is true.
